a brief history of etheric Classics (etc)

etheric classics began with an unfortunate event

in May 2016, the decentralized autonomous organization (DAO) held a token sale with the goal of establishing a blockchain based venture capital to fund future decentralized applications (dapps) in the Ethereum ecosystem

basically, Dao is a complex smart contract that operates in a decentralized way - computer code that automatically performs tasks between multiple parties when conditions are met

despite its ambitious goals and successful token sales, Dao's code has a major vulnerability that allows attackers to steal eth from decentralized organizations

the attacker took advantage of this vulnerability in June 2016, triggering the infamous Dao hacking event, and maliciously stole eth worth about US $50 million

there is no doubt that Dao hacking has shocked Ethereum community and made eth price drop from $20 to $13

after the Dao hacking, the Ethereum community has to choose from three options

< UL >
  • do nothing and try to bear the consequences of the attack; Or

  • start soft bifurcation to recover funds; Or

  • deploy a hard fork to recover the lost eth

  • both soft and hard bifurcations are significant network upgrades. However, soft fork allows users who are not upgraded to communicate with upgraded users, while hard fork is not backward compatible with previous versions

    as developers realize that deploying soft forks will expose the network to distributed denial of service (DDoS) attacks, Ethereum community decides to initiate hard forks to recover the funds lost in Dao hacking attacks

    although this scheme is supported by most people, a small number of people in Ethereum community oppose it. They think that "code is the law" and blockchain network should be unchangeable

    the failure of both sides to reach an agreement on the solution eventually led to the fragmentation of Ethereum blockchain

    those who tried to recover the lost eth chose the hard fork and opened the Ethereum (ETH) blockchain as we know it today, while another group stayed on the original Ethereum classic (etc) chain

    what problems does ethereal classic solve

    Ethernet classic (etc) is a blockchain platform that allows developers to deploy smart contracts and dapps

    although this function is the same as Ethereum (ETH), etc blockchain has two main differences

    first of all, Ethereum classic community opposes tampering with distributed ledger and supports the view that "blockchain network cannot and should not be modified"

    secondly, although there is no rigid upper limit on the total supply of eth, it is allowed to create 230 million etc at most by adopting the monetary policy of constant supply

    as a bonus item, ethereal classic launched Atlantis hard bifurcation last year to increase the interaction with Ethereum and improve the privacy protection of transactions through ZK snarks

    the trading platforms recommended by etc

    hot money, okex, AAX, etc

    2.

    At present, there are many channels for domestic users to buy Ethereum. Here are some common channels:

    < H2 > 1. Coincola is an over-the-counter trading platform for indivials to trade bitcoin

    coy Cola is affiliated to Hong Kong coincola limited, which is developed and operated by a professional international team, focusing on providing convenient and reliable blockchain services for global users. Coincola gathers global users and is committed to building a world-class blockchain asset platform

    in coy cola, people from different countries can buy bitcoin with their own currency. The seller of the website publishes the advertisement of selling bitcoin, and explains the payment method and exchange rate. You can choose to trade directly online according to the content of the advertisement. Bitcoin is stored in Ke Ying Cola's Internet wallet. You can transfer bitcoin directly

    2. How to buy eth

    < UL >
  • register the coincola account, and then click "buy" in the top menu of the home page to enter the advertisement list page

  • select the appropriate advertisement from the advertisement list and click "buy eth" to enter the transaction page

  • enter the amount of money to be purchased or the number of digital currency (please understand the message information of the other party, payment method, and transaction instructions of the platform before entering), click buy now, and the order confirmation pop up. After checking and confirming the information, click confirm purchase to enter the order page

  • in the chat box of the platform, you can inquire whether the other party is online according to the template statement, and make offline payment according to the collection information and collection method provided by the other party

  • after the completion of offline payment, click the mark that the payment has been completed at the first time (please complete this operation within 15 minutes at the beginning of placing an order, so as to avoid the payment cannot be recovered e to the cancellation of the order e to overtime), and then customize the input information in the chat box to confirm the payment and ask the seller to confirm the collection and release the digital currency

  • the progress bar in the top column shows that the goods have been received, indicating that the digital currency has arrived in the wallet. Make comments according to the seller's behavior, and click submit to complete the transaction

  • < / UL > < H2 > 2. C2C trading on trading platform

    with the rapid increase in the number of trading platforms and competitive pressure, many trading platforms will have their own C2C trading. Here we take the relatively large ZB trading platform as an example to illustrate

    What is C2C

    C2C transaction is a customer to customer transaction, which is guaranteed by the transaction platform. There are many such platforms, such as: Fire coin, otcbtc, bitpai OTC, etc., which are guaranteed by the platform and traded between users. We can simply understand it as: our shopping situation on Taobao is the same as that. In case of dispute, the platform will arbitrate. As long as the transaction is carried out according to the normal process, the security of the transaction is guaranteed

    2. ZB's C2C business

    ZB platform has two choices: QC and usdt. The basic logic is the same. There are many usdt platforms. QC is the feature of ZB, EXX and other platforms. Here we focus on QC

    < H2 > about QC

    QC is a token. At present, you may know more about usdt and bitcny. At present, there is a special area for QC transaction on ZB. Simply put, QC can buy all other digital currencies (BTC, ETH, EOS, etc.) on ZB. Therefore, after purchasing QC with RMB recharge, you can conct currency transaction on ZB station

    The advantage of the < H2 > QC token is that the exchange ratio between the < H2 > < UL >
  • and RMB is 1:1, which is easier to convert

  • purchasing other tokens with QC can be directly understood as purchasing RMB, and has an intuitive understanding of the currency price

  • it takes about half an hour to get to the account. It will take about two hours to get to the account in congestion

  • ZB platform is relatively reliable, and the reputation of ZB is still very good in the past

    How to operate C2C of ZB

    < UL >
  • log in to ZB trading platform and click "C2C trading" on the page

  • to get to the QC transaction page, you need to first bind your bank card. Then, in the buy QC interface, enter the quantity of QC you want to buy. At present, the ratio of QC to RMB is 1:1. Enter the purchase quantity and click "buy now"

  • after clicking "buy now", you will be prompted to complete the payment within 30 minutes. At the same time, payment information is generated. Please note that the payment must be made according to the prompt

  • < / UL > < H2 > official statement:

    business processing time 9:00-21:00. Non processing time orders will be processed at 9:00 the next day, and the payment will be completed within 24 hours after receiving the order

    this means that the merchant you paid will transfer QC coin to your account within 24 hours. According to my experience, you can get to the account in 2 hours ring the day

    < H2 > the following points should be paid attention to:

    1) make sure to use the newly bound bank card for transfer and payment

    2) note information (that 6 digit) must fill in

    3) do not use Alipay, WeChat and other transfers. p>

    4) do not fill in the opposite account incorrectly

    < UL >
  • about 1-2 hours, you can check whether your QC has arrived in the financial center

  • after the account is received, you can trade in the "QC" zone of the "spot trading". You can choose the transaction you want to buy and buy the order

  • 3. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)
    4. Whether a currency is counterfeit depends on whether it meets the basic characteristics of blockchain. Blockchain is divided into public chain and private chain. The public chain is a block chain based on the principle of decentralized open consensus, which has two characteristics: 1. Decentralized, single point can not be controlled; 2; 2. Open, all people or institutions can participate in any part of the blockchain ecology; Private chain or alliance chain is a local decentralized and non open block chain based on internal or self trust. It has two characteristics: 1. Local decentralization. For example, several banks run one node and have equal computing power; 2. In closed operation, only officially designated participants can participate in the core work of blockchain operation, and even block queries are limited or not open to the outside world at all; Ethereum started as a community project and is still on the road of decentralization. However, Ethereum chooses to become more and more decentralized and public chain like bitcoin. At present, Qube is the largest trading platform of Ethereum in China, followed by oke, and the trading volume of bitmex abroad is not small. Its recognition is second only to BTC.
    5.

    It does not belong to MLM

    Ethereum is an open source public blockchain platform with smart contract function, which provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum

    the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, to the effect of "next generation cryptocurrency and decentralized application platform", and began to develop through crowdfunding in 2014. The market value of Ethernet currency is second only to bitcoin, and it is the second largest encrypted digital currency in the world

    extended data

    bitcoin has created the first decentralized cryptocurrency, and has fully tested the feasibility and security of blockchain technology in more than five years. In fact, bitcoin's blockchain is a set of distributed database. If a symbol bitcoin is added into it and a set of protocol is specified, the symbol can be transferred safely on the database without trusting a third party. The combination of these features perfectly constructs a currency transmission system bitcoin network

    however, bitcoin is not perfect, and the scalability of the protocol is a deficiency. For example, there is only one symbol in the bitcoin Network - bitcoin, and users can't customize other symbols. These symbols can represent the company's stocks or debt certificates, which will lose some functions

    In addition, a stack based scripting language is used in bitcoin protocol. Although this language has some flexibility to realize functions such as multi signature, it is not enough to build more advanced applications, such as decentralized exchanges. Ethereum is designed to solve the problem of insufficient scalability of bitcoin

    6. If you have an okex account, you can trade in the currency area or the legal currency area.
    7.

    Generally speaking, digital goods ratio has nothing to do with MLM.

    MLM must first meet the following points:

    1. Pay a certain fee as the entry fee, whether you pay or spend money to buy procts as the entry condition

    2. The most basic thing is that the income mainly comes from pulling people, not from selling procts

    3. MLM can only be considered if you have to develop level 3 or above offline, and you can share the income of offline, you can also share the income of offline, you can also share the income of offline, you can also share the income of offline

    Finally, it developed into pyramid model

    Then set up a five level three-level system, so that the boss can get out of the game with millions

    you can compare this mode

    8. Did you buy Ethereum try on in the private website platform? This kind of thing is best sold on the state-owned official website, private ones are not fake
    9. In the past two years, what blockchain, bitcoin, Ethereum and token fire have been in a mess. The swindlers are the first! This cross-border credit rating project sounded so big last year. I thought I was going to enter the currency circle and have a good life. On impulse, I invested 50000 yuan in my down payment for buying a house! As a result, these swindlers have been selling coins for more than a year. They have cheated the big guys for so much money. The program of the big project has not changed. Now the official reply is that it will be online next month, that is to say, it will delay you for another may. Is there nothing in May? That completely shows that I fell into a pit. My down payment to you for the coffin is good! Although we cheated people blame us for being stupid, can the government manage and punish them?! I want to get something for nothing! At that time, the project will not be affected, and the money will certainly not come back. What can we do then? It's OK to send it to ya! They raise money illegally! Fraud!
